Description

Technical Field

[0001] This utility model relates to the field of oil injection equipment technology, and in particular to a resin bearing oil injection equipment with an oil injection angle adjustment joint structure. Background Technology

[0002] As an important component in mechanical transmission systems, the smoothness and lifespan of resin bearings largely depend on the quality of lubrication and maintenance. In daily maintenance, it is usually necessary to use oiling equipment to accurately inject lubricating oil into the friction pairs or designated oiling holes of the bearing to reduce wear and noise. However, as the structure of mechanical equipment becomes increasingly complex and compact, the installation positions of resin bearings often vary. Some are located deep within the equipment, while others are in inclined or narrow spaces, which places high demands on the flexibility of oiling operations.

[0003] Existing resin bearing lubrication equipment mostly uses fixed support frames and straight-through rigid or semi-rigid lubrication pipes. While these can meet the lubrication needs of conventional open locations, the angle and direction of the lubrication pipes are usually fixed and not adjustable, or the adjustment range is extremely limited. When faced with bearing lubrication ports in concealed locations or with tricky angles, operators often find it difficult to accurately align the lubrication pipe openings. Forcing the operation can easily lead to lubricating oil overflowing and contaminating the equipment, or even insufficient lubrication due to angle deviations, seriously affecting the lubrication effect of the bearing and the maintenance efficiency of the equipment. Therefore, this utility model proposes a resin bearing lubrication device with an adjustable lubrication angle joint structure to overcome the shortcomings of the existing technology. Utility Model Content

[0004] In view of the problems that existing resin bearing oiling equipment generally adopts a design with a fixed oiling pipe angle or a very small adjustment range, it is difficult to accurately align the oiling port of the bearing with a hidden location and a special angle, and the manual opening and cleaning and maintenance of the oil storage tank sealing cover integrated component is extremely laborious and inconvenient due to its heavy weight. The present invention aims to provide a resin bearing oiling equipment with an oiling angle adjustment joint structure that has been improved in structure and can effectively solve the above problems.

[0005] This utility model provides a resin bearing oil injection device with an adjustable oil injection angle joint structure, including a support frame, a limiting block, a hollow column, a first telescopic column, a support rod, a second telescopic column, a first bolt, a first nut, a second bolt, a second nut, a first rotating block, and an oil injection pipe. The top of the inner wall of the support frame has a sliding groove, the limiting block is slidably connected to the inner wall of the first sliding groove, the hollow column is slidably connected to the outer wall of the first sliding groove, the first telescopic column is slidably connected to the inner wall of the hollow column, the support rod is fixedly connected to the top of the first telescopic column, the second limiting groove is slidably connected to the outer wall of the second limiting groove, the first bolt is rotatably connected to the inner wall of the second telescopic column, the first nut is threadedly connected to the outer wall of the first bolt, the second bolt is rotatably connected to the bottom of the outer wall of the second telescopic column, the second nut is threadedly connected to the outer wall of the second bolt, the first rotating block is rotatably connected to the outer wall of the second bolt, and the oil injection pipe is fixedly connected to the inner wall of the first rotating block.

[0006] Preferably, the outer wall of the hollow column is provided with multiple limiting grooves, and the bottom of the inner wall of the telescopic column is slidably connected with a locking block. The locking block is slidably connected to the inner wall of the limiting groove. By the locking block cooperating with the limiting groove at different height positions, the multi-level height adjustment and stable locking of the support rod and the oil injection pipe in the vertical direction can be realized, effectively preventing slippage due to gravity or vibration and enhancing the reliability of equipment adjustment.

[0007] Preferably, a storage box is fixedly connected to the inner wall of the support frame, and an oil storage tank is fixedly connected to the inner wall of the support frame. A sealing cap is slidably connected to the top of the oil storage tank, and a fixing ring is fixedly connected to the bottom of the outer wall of the sealing cap. The storage box is used to orderly store and protect pipelines and components. The oil storage tank, as the main storage container for lubricating oil, together with the slidable sealing cap, ensures airtightness while providing a structural basis for subsequent opening, filling, and maintenance operations.

[0008] Preferably, a plurality of fixing blocks are fixedly connected to the top of the outer wall of the oil storage tank, a fixing column is fixedly connected to the inner wall of the fixing block, and a rotating block two is rotatably connected to the outer wall of the fixing column. The fixing blocks and the fixing column provide a stable rotation fulcrum for the rotating block two, ensuring the structural stability of the lifting mechanism under stress.

[0009] Preferably, the inner wall of the rotating block is threaded with a threaded post, the top of the threaded post is fixedly connected with a knob, and the bottom of the outer wall of the threaded post is threaded to the fixing ring. The knob drives the threaded post to rotate, and then the fixing ring and the sealing cover are driven to move vertically and smoothly through the threaded transmission, realizing a labor-saving and convenient opening operation, which greatly facilitates daily equipment maintenance.

[0010] Preferably, an oil pump is fixedly connected to the top of the sealing cap, and a transport pipe is connected to the top of the oil pump. A distribution tank is fixedly connected to the inner wall of the storage box. The end of the transport pipe away from the oil pump is connected to the distribution tank.

[0011] Preferably, the outer wall of the distribution tank is connected to an oil supply pipe, and the end of the oil supply pipe away from the distribution tank is connected to the oil injection pipe. The lubricating oil processed by the distribution tank is stably delivered to the oil injection pipe through the oil supply pipe, ensuring the smoothness and uniformity of the oil injection operation.

[0012] Preferably, the bottom of the inner wall of the support frame is provided with a circular groove, and the top of the storage box is provided with the circular groove. The design of the circular groove provides a neat channel for the power cord and oil pipeline inside the equipment, avoiding messy tangling of pipelines and improving the overall aesthetics and safety of the equipment.

[0013] This utility model has the following beneficial effects: 1. This utility model solves the problem of fixed oil injection pipe angle and difficulty in accurately aligning complex or hidden oil injection ports in existing resin bearing oil injection equipment by setting a joint adjustment structure consisting of bolts, nuts and rotating blocks at the end of the telescopic column. Loosening the nut allows the rotating block to be rotated, thereby driving the oil injection pipe to change the injection angle.

[0014] 2. This utility model solves the problems of limited adjustment range and unstable positioning of traditional equipment support structures by setting a sliding groove to cooperate with a hollow column for horizontal position movement, using a locking block to cooperate with a multi-level limiting groove to achieve graded fixation of vertical height, and using the sliding of the telescopic column in the limiting groove for fine adjustment of extension distance. It achieves the effect of being able to fully cover the oil injection area at different positions and heights and ensuring the stability and reliability of the support structure.

[0015] 3. This utility model solves the problem in existing equipment where the oil tank sealing cover is heavy due to the integration of components such as the oil pump, making manual opening and maintenance laborious and inconvenient.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] Example: Please refer to Figures 1 to 4 This utility model provides a resin bearing oiling device with an oil injection angle adjustment joint structure, which aims to solve the problem that the oil injection pipe angle of the existing resin bearing oiling device is relatively fixed, making it difficult to adapt to the oiling needs of bearings in different positions and angles.

[0020] Please refer to Figure 1 , Figure 3 and Figure 4As shown, the resin bearing oiling device with an adjustable oiling angle joint structure includes a support frame 1, which serves as the support and mounting base for the entire device. A groove 9 is provided on the top of the inner wall of the support frame 1, providing a guide path for the horizontal movement of the hollow column 11. A limit block 10 is slidably connected to the inner wall of the groove 9, limiting the range of movement to prevent detachment. The hollow column 11 is slidably connected to the outer wall of the groove 9, allowing for rough horizontal adjustment of its position. A telescopic column 17 is slidably connected to the inner wall of the hollow column 11, enabling vertical adjustment within the column to accommodate oiling operations at different heights. A support rod 18 is fixedly connected to the top of the telescopic column 17, connecting and supporting subsequent extension structures. A limit groove 21 is provided on the outer wall of the support rod 18, with a telescopic... Column 22, the telescopic column 22 can be telescopically adjusted along the length of the support rod 18 to change the working distance of the oil injection. Bolt 19 is rotatably connected to the inner wall of the telescopic column 22, and nut 20 is threadedly connected to the outer wall of bolt 19. Bolt 19 and nut 20 cooperate to lock the relative position of the telescopic column 22 in the limiting groove 21. Bolt 23 is rotatably connected to the bottom of the outer wall of the telescopic column 22, and nut 24 is threadedly connected to the outer wall of bolt 23. Rotating block 25 is rotatably connected to the outer wall of bolt 23. Rotating block 25, as a joint structure, can rotate around the axis of bolt 23. Oil injection pipe 26 is fixedly connected to the inner wall of rotating block 25. By loosening nut 24 and rotating rotating block 25, the angle of oil injection pipe 26 can be flexibly adjusted, thereby achieving precise alignment of the oil injection port of the resin bearing at different angles. Oil injection pipe 26 is used to deliver lubricating oil to the inside of the resin bearing.

[0021] To further address the positioning and stability issues of the oil injection pipe height adjustment, multiple limiting grooves 15 are provided on the outer wall of the hollow column 11. These grooves 15 are spaced apart along the vertical direction of the hollow column 11 and provide graded positioning points for height adjustment. A locking block 16 is slidably connected to the bottom of the inner wall of the telescopic column 17. The locking block 16 can slide horizontally inside the telescopic column 17. When adjusting the height, the locking block 16 is moved and inserted into the limiting groove 15 at different height positions. The cooperation between the locking block 16 and the limiting groove 15 restricts the vertical movement of the telescopic column 17, thereby fixing the telescopic column 17 at the required height. This multi-level locking groove structure ensures the stability of the support rod 18 and the oil injection pipe 26 at the working height and prevents accidental slippage due to gravity or vibration.

[0022] To ensure stable storage and transportation of lubricating oil inside the oil storage tank 5, a storage box 3 is fixedly connected to the inner wall of the support frame 1. The storage box 3 is used to accommodate the diversion component and protect the internal pipeline. An oil storage tank 5 is fixedly connected to the inner wall of the support frame 1. The oil storage tank 5 is used to store a large amount of lubricating oil. A sealing cover 6 is slidably connected to the top of the oil storage tank 5. The sealing cover 6 is used to close the top opening of the oil storage tank 5 to prevent impurities from entering and to maintain a clean internal environment. A fixing ring 12 is fixedly connected to the bottom of the outer wall of the sealing cover 6. The fixing ring 12 serves as a transmission connector to assist in the lifting and lowering of the sealing cover 6. The sealing cover 6 can slide vertically open or close at the top of the oil storage tank 5 to facilitate the addition of lubricating oil or cleaning and maintenance of the oil storage tank 5.

[0023] To facilitate easy opening of the oil storage tank 5, multiple fixing blocks 28 are fixedly connected to the top of the outer wall of the oil storage tank 5. Fixing columns 27 are fixedly connected to the inner walls of the fixing blocks 28, providing rotational support points. A rotating block 29 is rotatably connected to the outer wall of the fixing column 27, allowing it to rotate around the fixing column 27. A threaded column 30 is threadedly connected to the inner wall of the rotating block 29, serving as the main lifting drive component. A knob 13 is fixedly connected to the top of the threaded column 30, providing a control for the operator. The threaded column 30 is manually rotated. A retaining ring 12 is threadedly connected to the bottom of the outer wall of the threaded column 30. When the knob 13 is rotated, the threaded column 30 rotates accordingly. Since there is a threaded fit between the threaded column 30 and the retaining ring 12, and the retaining ring 12 is restricted from rotating and can only move with the sealing cover 6, the rotational motion of the threaded column 30 is converted into the vertical linear motion of the retaining ring 12 and the sealing cover 6. This allows the sealing cover 6 to be raised or lowered smoothly and effortlessly, effectively solving the problem of laborious manual opening caused by the weight of the sealing cover 6 and the components above it.

[0024] In a preferred embodiment, to achieve automatic delivery and distribution of lubricating oil, an oil pump 7 is fixedly connected to the top of the sealing cover 6. The oil pump 7 serves as a power source for drawing lubricating oil from the storage tank 5. A transport pipe 8 is connected to the top of the oil pump 7, which guides the drawn lubricating oil to the subsequent distribution unit. A distribution tank 4 is fixedly connected to the inner wall of the storage box 3. The distribution tank 4 receives and buffers the lubricating oil from the transport pipe 8. The end of the transport pipe 8 away from the oil pump 7 is connected to the distribution tank 4. The distribution tank 4 can balance the oil pressure and prepare for multi-path distribution. An oil delivery pipe 14 is connected to the outer wall of the distribution tank 4. The oil delivery pipe 14 is used to deliver the distributed lubricating oil to the oil injection end. The end of the oil delivery pipe 14 away from the distribution tank 4 is connected to the oil injection pipe 26. The lubricating oil is sprayed out through the oil injection pipe 26 to complete the oil injection operation.

[0025] As another preferred embodiment, in order to facilitate the organization and routing of the power cord and pipeline of the equipment, a circular groove 2 is provided at the bottom of the inner wall of the support frame 1 and a circular groove 2 is provided at the top of the storage box 3. The circular groove 2 is used for cables or oil pipes to pass through, to prevent the pipelines from being messy and tangled, and to ensure that the pipelines are neatly routed, thereby improving the overall aesthetics and safety of the equipment.

[0026] Working principle: When it is necessary to perform oil injection on the resin bearing, the horizontal direction is initially adjusted according to the specific position of the bearing. The limiting block 10 slides in the slide groove 9, which drives the hollow column 11 to move along the slide groove 9 at the top of the support frame 1 to the appropriate position. Next, adjust the vertical height by manually moving the telescopic column 17 to slide inside the hollow column 11, aligning the locking block 16 with and locking it into the corresponding height limiting groove 15, and using the locking block 16 and the limiting groove 15 to fix the support rod 18 at the predetermined height. Then, make a fine adjustment to the oil injection distance. Loosen the nut 20 on the bolt 19 and slide the telescopic column 22 to extend and retract within the limiting groove 21 of the support rod 18. After determining the horizontal extension distance of the oil injection pipe 26, tighten the nut 20 to lock the telescopic column 22. The key oil injection angle adjustment is achieved through the joint structure. Loosen the nut 24 on the bolt 23, and the rotating block 25 can rotate around the bolt 23, causing the oil injection pipe 26 to deflect to the optimal oil injection angle, so that the oil injection pipe 26 is precisely aligned with the bearing gap. After the adjustment is completed, tighten the nut 24 to keep the angle fixed. When the oil pump 7 is started, the lubricating oil in the oil storage tank 5 is pumped to the distribution tank 4 through the transport pipe 8 under negative pressure. The distribution tank 4 buffers and distributes the lubricating oil, and then delivers it to the oil filling pipe 26 through the oil delivery pipe 14, thus completing the oil filling. When it is necessary to add lubricating oil to the oil storage tank 5 or clean its interior, there is no need to move the sealing cover 6 with effort. Just rotate the knob 13. The knob 13 drives the threaded column 30 to rotate. Since the threaded column 30 is threadedly connected to the fixed ring 12 and the fixed ring 12 is restricted from rotating, the rotation of the threaded column 30 drives the fixed ring 12 and the connected sealing cover 6 to rise smoothly along the top of the oil storage tank 5, so as to achieve easy opening.
